Title: Inspection method for apron link
Inventor: ISHIKAWA HIROAKI
IPC: B66C19/00
Filed: 1990-03-27
Abstract: PURPOSE:To accurately find durability and prevent trouble such as breakage by constituting the method so that stress value of an apron link at working is compared with a calculated stress value to inspect durability of the apron link. CONSTITUTION:Stress applied on an apron link 1 at working is measured with a strain gauge stuck on the apron link 1. Simultaneously, weight of bulk material held with a bucket 2 is measured. As the measuring means, current value of a motor driving the bucket 2 and the like is considered, and stress applied on the apron link 1 is calculated based on the weight. The stress value of the apron link 1 at working is compared with the calculated stress value, when the actual stress value is under the calculated stress value, the apron link 1 is judged to have durability, and when the actual stress value is over the calculated stress value, it is judged necessary to be repaired.
